ABSTRACT
OBJECTIVE:
Aim of the study was to evaluate efficacy and efficiency of 180-watt Green-Light XPS (GL-XPS) laser photoselective vaporization of the prostate (PVP) in patients under 5-Alpha-Reductase Inhibitors (5ARI) treatment. PATIENTS ANDMETHODS:
A consecutive series of patients with lower urinary tract symptoms due to benign prostatic enlargement treated by PVP with the GL-XPS were enrolled. Patients were divided in two groups according to the chronic use (>6 months) of 5ARI. These two groups were compared on lasing density (kilojoules per prostate volume), vaporization efficiency (prostate volume per lasing time), vaporization power (kilojoules per lasing time), Prostate Specific Antigen (PSA) reduction from baseline, symptom score change from baseline and uroflowmetry parameters improvement. Follow-up was performed at 3, 6 and 12 months with International Prostate Symptom Score, Uroflowmetry parameters and PSA.RESULTS:
Overall 193 patients were enrolled. Out of them 87/193 (45%) were on 5ARI treatment. No significant differences were recorded between the two groups at baseline. Median age was 68 years old and median prostate volume was 60 ml. In terms of laser efficiency, no statistically significant differences were recorded in terms of lasing time (25 min vs. 24.5 min; p>0.05); energy used (250 kJ vs. 221 kJ; p>0.05), lasing density (6.8 kJ/ml vs. 6.6 kJ/ml, p>0.05), vaporization efficiency (1.4 ml/min vs. 1.3 ml/min, p>0.05) and vaporization power (9.6 kJ/min vs. 9.4 kJ/min; p>0.05). Finally, no significant differences were also recorded postoperatively in the two groups in terms of PSA reduction, improvement in symptom score and uroflowmetry parameters (p>0.05).CONCLUSIONS:
Thirty-seven efficacy and efficiency outcomes were not statistically different between the two groups. 5ARI does not reduce the performance and ability of the 180-watt Green-Light XPS laser system.
